Abstract：Relay protection is to protect the safe operation of the Metro Power System. It's setting value is closely related to the load size and load changes. To ensure that the multi-set relay protection is accurate, the metro power supply system must be equipped with a perfect protection information management system, to strengthen setting, testing and management of protection value. Based on the structure and operation mode of metro AC power supply system, this article described a set of Protection Information Management System which with "Metro Power" features, to achieve the automatic value check, dangerous warning, rationalization of the proposed recommendations, fault waveform management and other functions. The system also implemented the top-level design and modular thinking, and highlighted the particularity and professionalism of the Metro power system. Finally, a typical example is used to illustrate the verification function based on the RTDS simulation platform.
